Group:
Eudicot
Estimated genome size:
1.5 m in height
Size:
1.5 m in height
Distribution:
Brunia noduliflora occurs from the Cederberg southwards to the Cape Peninsula and eastwards as far as the Cockscomb in the Groot Winterhoek Mountains of the Eastern Cape, at altitudes from near sea level to approximately 1 500 m.
PromethION Sequencing Report:
Output:
39.88 Gigabases
Approximate N50:
16.91 kilobases
Draft Genome Assembly Statistics:
Genome Length:
0.72 Gigabases
BUSCO completeness score (single and duplicated genes):
97.40% [S: 47.0%, D: 50.0%]
Importance:
Brunia noduliflora is the most widespread species in the subgenus Brunia and occurs across diverse fynbos habitats in the Cape Floristic Region. Its broad ecological range makes it valuable for studying diversification and adaptation within the Bruniaceae.
Group:
Eudicot
Estimated genome size:
Size:
3-5 cm high, about 10 cm in diameter
Distribution:
Endemic to a single valley in the Western Cape and restricted to disjunct sites on quartzite pavements.

Importance:
The Red List of Southern African Plants notes that the species is range-restricted species (EOO 260 km²) and 'declining due to ongoing habitat loss and degradation'. A recent publication by Milton et al. (2024) studied eight populations and concluded that grazing and climate change appear to be contributing to declines in this endemic habitat specific dwarf succulent, already threatened by land transformation and poaching in the Succulent Karoo hotspot of South Africa.
